Estimating Premorbid Ability in Rehabilitation Patients Using the Test of Premorbid Functioning and Wide Range Achievement Test–Fourth Edition

Abstract

Objective: This study examined premorbid ability estimate concordance using Test of Premorbid Functioning predicted Full Scale Intelligent Quotient (TOPF-IQ) and Wide Range Achievement Test–Fourth Edition Word Reading (WRAT4-WR). Method: The sample ( N = 145) was 28% female with average age and education of 40.6 and 13.2 years, respectively. Outpatient neuropsychological evaluations were conducted in a rehabilitation setting. Measures included the TOPF, WRAT4-WR, Wechsler Adult Intelligence Scale–Fourth Edition, and other neuropsychological tests. Non-WAIS measures defined impairment groups. Analyses included t tests, pairwise correlations, concordance correlation coefficients, and root mean square differences. Results: TOPF-IQ, WRAT4-WR, and Full Scale Intelligent Quotient scores were not significantly different but were lower than normative mean. TOPF-IQ and WRAT4-WR showed acceptable agreement (concordance correlation coefficient = .92; root mean square difference = 5.9). Greater premorbid–current ability differences were observed in the impaired group. TOPF-IQ and WRAT4-WR showed lower but similar agreement with Full Scale Intelligence Quotient in the unimpaired group. Conclusions: Findings support the WRAT4-WR in predicting premorbid ability in rehabilitation settings.

“…A comprehensive neuropsychological test battery was used to assess the following cognitive domains: (1) executive function, assessed by Trail Making Test (TMT) part B (Corrigan & Hinkeldey, 1987), and the Delis-Kaplan Executive Function System (D-KEFS) Tower test (Levin et al, 1994); (2) language, assessed by phonemic (FAS) and semantic (ANIMALS) fluency (Tombaugh et al, 1999); (3) complex psychomotor processing speed, measured with the Symbol Digit Modalities Test (SDMT) (Smith, 1982) and TMT part A (Corrigan & Hinkeldey, 1987); (4) auditory attention, measured with the Wechsler Adult Intelligence Scale-IV (WAIS-IV) Digit Span (Hartman, 2009); (5) verbal memory, assessed by the Rey Auditory Verbal Learning Test (RAVLT) (King et al, 1998; Lezak et al, 2004). The Wide Range Achievement Test-4 (WRAT-4) Reading subtest was used to estimate participants’ premorbid (or pre-ARF) intellectual ability (Rolin et al, 2021). To minimize potential mental fatigue, the comprehensive neuropsychological test battery used in this study was selected to be completed within approximately 1 hour.…”
